Are you sure that it is version 2.0 and not 1.0?
The link to the photos will make finding the problem easier.
D11 and D14 do not have polarity, they can be installed in any position.No, GPS will not work on NCM109 board, but can work on NCS314 or NCS312 (together with Arduino Mega).
This connector for temperature probe DS18B20:

https://photos.app.goo.gl/H1uAii3oMGdoDmFj6You must select firmware for NMC109 board depending on the top board model (tubes board):
1K revision only for boards with 1 kOhm resistors at anode circuit. Here a places for these resistors:

On this board resistors marked as 103 this mean 10 kOhms (not 1 kOhm).To turn off tube You need to send 64 bit of zeros via SPI interface.
int nZero=0; SPI.transfer(nZero); //16bits SPI.transfer(nZero); //+16bits - 32bits SPI.transfer(nZero); //+16bits - 48bits SPI.transfer(nZero); //+16bits - 64bitsI think the best solution is to change the function ‘void doIndication()’ at ‘doIndication314_HW2.x.ino’ file.
1. Remove U4 and try to power on the board again.
2. If this does not not help compare your board with this: https://photos.app.goo.gl/mZEVxUJ5zWN7Thk17
3. Please send us some photos of your board in the highest possible resolution, made in good lighting. We will try to identify the problem from the photos.

(or any other convenient for you)Yes, the shield based on bare NCS314 board will work with any Arduino Mega revisions, including rev3.
